Publication number: 20070047250Abstract: A headlamp including a first addition reflector 34 and a second addition reflector. The first addition reflector is arranged between a light source bulb 22 and a shade 32 and reflects light that is sent from a light source 22a toward a front region in a bulb insertion direction on a reflecting face 24a of a main reflector 24. The second addition reflector 36 reflects light, which is reflected on the first addition reflector 34 being sent from the light source, to the optical axis Ax, side. Reflecting faces 34a, 36a of the addition reflectors 34, 36 can be divided into upper stage reflecting portions 34a1, 36a1 and lower stage reflecting portions 34a2, 36a2.Type: ApplicationFiled: August 18, 2006Publication date: March 1, 2007Inventor: Masao Kinoshita

Patent number: 7168832Abstract: As the annular translucent member, an annular lens formed from a peripheral edge portion of a convex-meniscus lens is disposed between a projection lens and a reflector along an outer peripheral edge of the projection lens. Direct light from a light source toward a space beyond the outer periphery of the projection lens is caused to illuminate forward of the lamp by the annular lens, thereby effectively utilizing light source luminous flux. In relation to the above, a shape of a back surface of the annular lens is formed into a spherical surface having its center at a luminescence center of the light source. Accordingly, direct light from the light source can travel straight without being deflected by a back surface of the annular lens, whereby a light deflection angle on a front surface of the annular lens can be calculated easily and with good accuracy.Type: GrantFiled: February 24, 2005Date of Patent: January 30, 2007Assignee: Koito Manufacturing Co., Ltd.Inventors: Motohiro Komatsu, Masao Kinoshita, Masahito Naganawa, Kenichi Takada, Mitsuyuki Mochizuki

Publication number: 20050007020Abstract: An automotive discharge bulb having a light emitting tube includes a ceramic tube with paired electrodes oppositely placed, and contains a light emitting material and starting rare gas. A transversal section of the ceramic tube is longitudinally elongated. Because the capacity of an enclosed space of the ceramic tube is small, after discharging begins, the enclosed space temperature increases. Consequently, the ceramic tube has a good luminous flux rising characteristic. Because of the small surface area of the ceramic tube, the load imposed on the wall surface increases. Consequently, the ceramic tube has good luminous efficiency. In the ceramic tube having a longitudinally elongated transversal section, an arc generated into an upwardly convex shape and the tube wall do not make contact. Thermal shock resistance required of the ceramic tube is alleviated, durability is enhanced, and the ceramic tube is made of a ceramic material hitherto unusable.Type: ApplicationFiled: May 25, 2004Publication date: January 13, 2005Inventors: Toshiaki Tsuda, Masao Kinoshita

Publication number: 20040174121Abstract: In a discharge bulb, an arc tube is fixed and held by an insulating base in the rear side such that the arc tube elongates forward. In the arc tube, an enclosed space is formed by sealing both ends of a straight cylindrical ceramic light emitting tube, electrodes are opposingly disposed therein, and the enclosed space is filled with a light emitting substance and starting rare gas. A light blocking film is disposed in part of a glass shroud surrounding the arc tube that corresponds to a sealed rear portion. To design effective reflecting surfaces, a rectangular light source image is projected onto a luminous distribution screen. Particularly, an upper end portion close to a horizontal cutoff line in the rectangular light source image projected in the vertical direction is clear. Even when the radially projected light source image approaches the elbow portion, a glare-free luminous distribution is formed.Type: ApplicationFiled: January 5, 2004Publication date: September 9, 2004Applicant: KOITO MANUFACTURING CO., LTD.Inventors: Toshiaki Tsuda, Masao Kinoshita

Patent number: 5392110Abstract: In a signal processing circuit, a height arithmetic circuit obtains a measured value of a height of an object by using the principle of triangulation from a second light receiving signal which is transmitted from a second photodetector of position detecting type thereto. An error arithmetic circuit acquires a measurement error by using the principle of triangulation from a first light receiving signal which is transmitted from a first photodetector of position detecting type thereto. A correction circuit calculates a correct height of the object by subtracting an output signal of the error arithmetic circuit from an output signal of the height arithmetic circuit.Type: GrantFiled: April 16, 1993Date of Patent: February 21, 1995Assignee: NEC CorporationInventors: Masayuki Yojima, Masao Kinoshita
